Ultra-wideband Radar Human Activity 4D Imaging Dataset    2022 No.1

Guest Editor: Jin Tian

Ultra-wideband radar human activity 4D imaging dataset (UWB-HA4D) 1.0 includes 2757 groups human activity data, which are captured by detecting and imaging through Ultra-wideband MIMO radar system. The system working at 1.78 – 2.78 GHz, it adopts the stepped frequency continuous wave (SFCW) signal as transmitted signal, and the array antenna of this system is a two-dimensional array with 10 transmitters and 10 receivers.

The dataset contains the activity data for 11 human targets, including 10 common activities, such as standing, sitting, waving, boxing, walking, kicking. It also contains 3 data collection scenarios: free space scenario without occlusion, 3 cm thick plastic plate occlusion scenario and 27 cm thick brick wall occlusion scenario. In this dataset, the activity data of 9 human targets in the free space scenario was set as the training dataset, and the activity data of the other 2 human targets was set as the test dataset. Meanwhile, the activity data of two occlusion scenarios are set as the test dataset to evaluate the environmental adaptability of the system. 

In addition, the dimension of radar data in this dataset is 40×64×64×64, where 64×64×64 is the size of 3D radar image, 40 is the frame number of 3D radar images, and the data format is mat.

For details of the dataset, you can see the paper “UWB-HA4D-1.0: An Ultra-wideband Radar Human Activity 4D Imaging Dataset” and “The instruction of Ultra-wideband Radar Human Activity 4D Imaging Dataset”.
